I just came across Jada Toys new Nano Hollywood Rides at Walmart that would be great for OG scale minis.
Online I've seen them referred to as 1/64 and even 1/24 scale, but they measure out to 1.5 inches just like original Micro Machines.
There are currently 2 assortments of 3 cars each making 5 sports cars and 1 truck (Optimus Prime). I see the back ad for the Fast & Furious set shows an additional 3 cars (2 sports cars 1 F-150) but I didn't find that on the shelves and don't see any online listing for those YMMV.
